Welcome to the School of Biological Sciences


Biological Sciences - Behavior, Ecology, Evolution & Systematics

The students, faculty, and post-doctoral fellows that comprise the Behavior, Ecology, Evolution, and Systematics (BEES) section focus on research questions that range widely over the disciplines of ecology, evolution, behavior, physiology, and systematics.

We emphasize an integrative, collaborative approach to research not only among the members of the BEES section, but also with members of the other sections in the School of Biological Sciences and with faculty and students at other universities. Research within the BEES is conducted across different levels of biological organization, from genes to individuals, populations to communities. We address fundamental questions concerning the nature of evolutionary change, interactions between organisms and their environment, the distribution and abundance of living things, and the conservation of organisms and restoration of their ecosystems.
